CURT Echo Bluetooth Mobile Trailer Brake Controller — 7‑Way, 1–2 Axles, App-Controlled Plug-and-Play Proportional Braking

Designed for vehicle owners who tow different trailers or use multiple tow vehicles, the Echo replaces bulky dash-mounted controllers with a compact device that plugs into a standard 7-way RV blade socket. Once connected, the controller links wirelessly with the Smart Control app on iOS or Android so you can set brake profiles, monitor brake status, and quickly swap the unit between vehicles without permanent wiring. Built for outdoor use, the Echo’s potted electronics and retention locking features help it resist moisture, vibration, and rough handling.

How does Echo connect to my phone and vehicle?

The Echo pairs to your smartphone over Bluetooth using CURT’s Smart Control app. Installation requires no tools — simply plug the Echo between the vehicle and trailer 7-way connectors, secure the retention strap, and open the app to pair and configure profiles.

• Bluetooth pairing with iOS and Android via Smart Control app.
• Plugs into industry-standard 7-way RV blade socket — no hardwiring.
• Retention strap and locking tab secure the connector in the vehicle socket.
• Store profiles for multiple vehicle-trailer combinations for fast setup.

What braking capabilities and towing setups does Echo support?

Echo manages proportional braking for trailers with one to two axles (two to four electric brakes). Its tri-axis accelerometer ensures smooth, responsive braking whether you’re going up, down, or across varied terrain.

• Operates 2–4 electric trailer brakes (1–2 axles).
• Tri-axis accelerometer for proportional braking response.
• Compatible with vehicles that have cruise control and ABS systems.
• Brake adjustments are made in the app while the vehicle is stationary for safety.

Is Echo durable enough for outdoor towing conditions?

The Echo uses a potted enclosure where internal electronics are encapsulated in resin to keep out dirt and moisture and to reduce vibration-related stress. The compact housing and locking connector help maintain a reliable electrical connection in adverse weather.

• Potted circuit board protects internal components from moisture and dust.
• Resilient shell and epoxy filling reduce vibration damage.
• Connector locking tab and storage cap with strap improve retention.
• Portable design suits fleet use or owners with multiple towing vehicles.

How do I install and move Echo between vehicles?

Installation is a true plug-and-play experience: unplug the trailer 7-way from the vehicle, insert Echo, then reconnect the trailer to the Echo. To move it, unplug the Echo and repeat the process in the next vehicle — the app simply recalls stored profiles for fast setup.

• No tools or permanent wiring required; inserts between 7-way connectors.
• Cap stores retention strap when not in use to protect the port.
• Multiple saved profiles let you switch trailers or vehicles quickly.
• Smart Control app provides setup guidance and brake fine-tuning.

Who this is for: The CURT Echo 51180 fits drivers who tow utility, boat, pop-up, or small travel trailers with electric brakes and want a modern, removable controller that avoids dash installations. It’s ideal for fleet operators, contractors with multiple tow vehicles, weekend boaters, and anyone who prefers managing brake settings from a phone. Note: requires a vehicle and trailer with matching 7-way RV blade connectors and a compatible iOS/Android device; adjust settings only when the vehicle is parked.
